Description
The Atmel® AT24C01D/02D provides 1,024/2,048 bits of Serial Electrically Erasable and Programmable Read-Only Memory (EEPROM) organized as 128/256 words of eight bits each. The device’s cascadable feature allows up to eight devices to share a common 2-wire bus. These device are optimized for use in many industrial and commercial applications where low-power and low-voltage operation are essential. Both devices are available in space-saving 8-lead SOIC, 8-lead TSSOP, 8-pad UDFN, 8-lead PDIP(1), 5-lead SOT23, and 8-ball VFBGA packages. The entire family of packages operates from 1.7V to 3.6V.
